摘　　要：以实际工程项目为例,研究击实试验在制样配水、击实后密度控制方面存在的问题和对试验结果的影响;分析不均匀原状土样在制备直接剪切试验试样时出现的问题和对样品不同配置方式进行试验时对试验结果的影响,为类似项目参考与借鉴。In this paper,according to my own experience in geotechnical test and combined with practical engineering projects,the problems of sample preparation and water distribution,density control after compaction test and their influence on test results are studied and analyzed.This paper studies and analyzes the problems in the preparation of non-uniform undisturbed soil samples for direct shear test and the influence on the test results when the samples are configured in different ways,which can be used for reference of similar projects.
